Verdict
The clearest difference is in-app purchases: Crystal Stack Tap at none against Penguin Diner 3D's 7. Crystal Stack Tap also leads on update cadence (fortnightly vs every 2 months). Penguin Diner 3D's advantage is iOS requirement (13.0 vs 15.1). On price, ads and device support there is nothing between them.
